Abstract: An optical part includes a quantum dot film layer, a lower transparent film layer, and an outer protective film. The quantum dot film layer includes an upper surface, a lower surface, and a lateral surface. The lateral surface connects the upper surface with the lower surface, and the quantum dot film layer is a film containing light emitting semiconductor nanoparticles. The lower transparent film layer is disposed on the lower surface of the quantum dot film layer. The outer protective film directly or indirectly covers the upper surface of the quantum dot film layer, and extends to cover the lateral surface of the quantum dot film layer.

Abstract: Disclosed are a light-emitting device with quantum dots and a manufacturing method thereof. The light-emitting device includes a light-emitting diode chip, a transparent barrier layer, a quantum dot film, and a transparent protective layer. The transparent barrier layer is disposed on the light-emitting diode chip. The quantum dot film is disposed on the transparent barrier layer, such that the light-emitting diode chip is separated from the quantum dot film by the transparent barrier layer. The transparent protective layer is disposed on the quantum dot film, such that the quantum dot film is encapsulated between the transparent barrier layer and the transparent protective layer.

Abstract: A method for enhancing anti-abrasion of a belt of a treadmill and an apparatus for practicing the method are disclosed herein. As processing the belt, the belt is installed in the apparatus and a driving device of the apparatus can move the belt. A distributing device of the apparatus scatters solid lubricative material on the surface of the belt. As the belt being moved, the lubricative material is melted by a heating device of the apparatus. When the belt is moved to leave the heating device, the melted lubricative material coagulates and engages with the surface of the belt.

Abstract: A tool box includes a casing with at least one open side for a plurality of boxes pivotally received therein. A link is pivotally connected to the boxes and located at a distance from the pivotal point of the boxes. An activation member is pivotally connected to one of the boxes and has a slot for receiving a boss extending from the link so that when pivoting the activation member, the link pivots the boxes to open. A spring is connected between the activation member and the casing so as to close all the boxes by pulling the activation member.

Abstract: This invention is a moving-character sound structure, involving mainly a mechanical unit. On the surface of the mechanical unit is an animal character. The eyes and mouth of the character are movable. The eyes and mouth of the character are connected to a transmission mechanism composed of a swing rod, a spring and a motor. Inside the mechanical unit are various circuits for radio, tape recorder, vocal IC, karaoke, and a driving circuit. When the push keys on the mechanical unit are pushed to select specific sound function giving off sound, the driving motor analyzes the specific frequency and activates the motor to rotate intermittently, causing the eyes and mouth of the character to open and close intermittently.
